Add `-configuration` options to `clean` target in `Makefile`
Add `-configuration` options to `clean` target in `Makefile`

`xcodebuild clean` uses `Debug` configuration without `-configuration`
option, and cleans directories that used by `Debug` configuration. But
`make install` uses `-configuration Release` by scheme of project.

By this change, `clean` cleans all directories that used by `Debug`,
`Release` and `Test` configurations.
